Stabilize Soil with Polyurethane

Arkansas Infrastructure

In Arkansas, we often have structural issues that occur due to unstable or eroded soil around infrastructure. This can result in damage to homes and businesses. Other causes of unstable soil conditions can be attributed to improper soil compaction, soil erosion, and plumbing leaks. In fact, these expanses destabilize the structures and foundations which result visibly in cracks, potholes, sinkholes, and damage that can take its toll on private property like homes and public assets like pipelines, roads, sewers, bridges, and other structures. Here are some common conditions:


Erosion of the soil usually occurs when water, wind, or human action moves dirt, soil, or rock. Soil erosion is the displacement of the upper layer of the soil. It’s a natural process that can go on unnoticed due to rains or plant growth but sometimes it can be a dramatic event such as a landslide.

Poor Compaction

When the construction of roads, homes, and infrastructure occurs it is imperative that the soil beneath has been properly compacted. If soil isn’t compacted, concrete can settle and crack. Some soil types with high clay or excess salt are more easily compacted whereas soil with high water content can have problems with compaction. Sometimes the soil isn’t properly compacted during the construction process and it leads to problems down the road,

Freezing and Thawing

When the water in the soil freezes it expands and as it thaws it contracts causing movement in the soil. It can loosen soil and increase soil instability.


Organic material in the soil is broken down over time with the decomposition and this leads to changes in the soil and soil instability.

Stabilize Soil with Polyurethane Solutions

So how can polyurethane help stabilize your soil? To put it simply, polyurethane can be injected into the soil to strengthen and stabilize it. It’s a quick process and it is cost-effective. Additionally, the process is also safe for the environment. Deep polyurethane injection is a permanent solution to stabilize the soil. It decreases the permeability of the soil and also increases the load-bearing capacity above the soil so structures built above that soil can be safe and sound. Where can you use polyurethane to stabilize the soil? There are several areas that can benefit from the application:

  • Commercial Foundations
  • Slab Foundations
  • Roads
  • Bridges
  • Highways
  • Tunnels
  • Patios
  • Sidewalks
  • Driveways
  • Pools
  • Porches
  • Railroad Tracks
  • Parking Lots
  • Airport Runways

Soil Stabilization with Polyurethane Foam

Oftentimes, many people wonder how the process of polyurethane repair works. Firstly, penny-size holes are strategically drilled in the affected area based on the location, area, and scope of the repair. Secondly, a two-part polyurethane mixture is mechanically injected through the hole utilizing carefully calibrated injection equipment. Then, underneath the concrete, a chemical reaction occurs where the two elements mix to create an expanding foam. Consequently, the foam fills all voids in the surrounding soil and stabilizes loose and non-compacted soil while expanding to create the lift. Then, enough material is injected into the troubled areas until the desired height is achieved and the concrete has returned to its original place. The holes are then filled with a high-density cement-type grout and finished to match the existing concrete. As a result, you won’t even know that there was a repair to the concrete.
